Since seating near to the lands is prefered, might there be some accuracy gains under those circumstances with a RN since the ogive would reach the lands much sooner?

This is what I found, as a rule r.n. shoot more accurate.

I have noticed that in SOME of my rifles also,especially with cast bullets,except for the 2 Lee designs made for the 7.62x39,these are Both super accurate in my 30-06 (12 gr.red dot,wlr,rem cases)and my 308 win (10 gr. red dot,wlr,win cases)the only other cast bullet that comes close is Oregon Trail`s 170gr gcfn designed for the 30-30.still using red dot it is a shooter.these are my winter squirrel loads and they work very well,less meat damage than .22 l.r. due to the hard alloy bullets.my 308 barrel is off an FR-8 so it has some freebore.
